Locking the computer
Locking the computer cover
Locking the computer cover helps prevent unauthorized access to the
inside of your computer. Your computer features a padlock loop so that
the computer cover cannot be removed when a padlock is installed.
Attaching a Kensington-style cable lock
You can use a Kensington-style cable lock to secure your computer to
a desk, table, or other nonpermanent fixture. The cable lock connects
to the security-lock slot at the rear of your computer. Depending on the
type selected, the cable lock can be operated with a key or
combination. The cable lock also locks the buttons used to open the
computer cover. This is the same type of lock used with many
notebook computers. You can order such a cable lock directly from
Lenovo by searching for Kensington at:
